IMPROVEMENT IN VENTILATING ATTACHMENTS TO STOVES.

Specification forming part of LettersPatent No. 164,259, dated June 8, 1875; application filed May 14, 1875,

lTo all whom it may concern:

Be it known that I, CHARLES CARTER, of

lthe city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in a Ventilating Attachment to a Stove, Heater, or other apparatus in which combustion is carried on; and I do hereby declare the following to be a clear and exact descriptionof the nature thereof, sufijcient to enable others skilled in the art to which my invention appertains to fully understand, make, and use the same, reference being had to the accompanying drawings making part of this specification, in which- Figure lis a longitudinal vertical section of the device embodying my invention. Fig. 2 is a transverse vertical section in line m m, Fig. 1. Fig. 3 is a top view of the portion below the line y'g/{Fig' 2.

Similar letters of reference indicate corresponding parts in the several figures.

rEhe object of my invention is to establish and secure a circulation of air in one or more rooms in dwellings or other structures, in such a manner that the whole of the air which may have become contaminated by use, and rendered foul and untit for further respiration, may be removed in a given time, and its place taken by the introduction of a supply of properlywarmed pure air.

The invention consists in a pipe which communicates with a Ventilating-register, and is inclosed in an air-pipe communicating with the atmosphere and an apartment, whereby the pure air in the latter pipe is warmed, which not only serves to draw it into the space-between the two pipes, but gives it a force to drive it to the ceiling or upper part of the apartment, or hot-air chamber of a heater, the contaminated air being directed to the reser` voir of a combustion apparatus, so as to be utilized or passed off.

The invention further consists in a provision for directing the contaminated air either under the fuel of a stove, heater, or other apparatus for carrying on combustion, so as to increase the draft or assist combustion, or over the fuel, in case combustion is too active and needschecking, or both under and over the fuel for regulating combustion as maybe necessary or desirable.

It also consists in a reservoir, with which communicates the pipe for contaminated air, and the pipes which direct said air above and below the fuel, in connection' with a damper which is adapted to close the pipe for contaminated air, so that, in the event of raking the tire, the dust thereof will be directed to the exit-liuc.

Referring to the drawings, A represents an apartment, in which is located a stove, heater, or other apparatus, B, in which combustion is carried on, said apparatus being hereafter known as the combustion apparatus. C represents the veutilatingregister of the apartment, which is located near the lower portion thereof, and with the same communicates a pipe, D, which passes through or under the floor of the apartment, and opens into a reservoir or chamber, E, formed adjacent to the ash-pit A', or other portion of the combustion apparatus. Surrounding the pipe D, and communicating with the atmosphere, is a pipe, F, which opens into the base G of the apparatus B. Vithin the reservoir E there are arranged two pipes, H J, both of which communicate with said reservoir. The pipe H communicates with the ash-pit A by means of an opening, c, and the pipe J communicates with a pipe or flue, K, which leads into the combustion-chamber L at a point over the space occupied by the fuel. M represents a damper, which is arranged within the reservoir E, and its handle is conveniently situated for operation. The pipe D projects somewhat into the reservoir E, and has an opening or communication, b, at the lower end. The pipe H has an opening, d, at its lower end, and the pipe J has also an opening, c, at its lower end. rPhe damper M is arranged vertically in the reservoir, and hasv a sliding motion, so as to cover and uncover the openings d c of the pipes H J, and the opening b of the pipe D.

The operation is as follows: The warm air of the apartment ascends and displaces the contaminated air therein, which latter descends and is directed into the ventilating-register G 'and pipe D, and thence passes into the reservoir E. The fresh or pure air enters the pipe whereby said fresh air is drawn intothe space between the two pipes D E, and has imparted to it a force that drives it into the apartment and to the ceiling or upper portion thereof',

the entrance therein being through the openings in the base Gr of the apparatus B, or directly into the apartment, and, if desired, it' may be directed into the hot-air chamber of a heater. From the reservoir E the' contaminated air may be utilized to assist or increase combustion by being passed under the grate of the apparatus through the opening a, which communicates with the pipe H. For this pur-v pose the damper M is forced in, so as to cover or close the opening e of the pipe J, whereby. tlieair enters the pipe H, andv thus `passes to the ash-pit A.

When the re is too active 'or needs'checking, the damper is drawn out, so as to cover, the opening cl of the pipe H, whereby there'is: a communication between the pipe J and pipe: vor flue K, and the air then passes through the 'pipes J and K into the combustion-chamber L f over the fuel. For some purposes the air will be required to be passed both above and be-g -1ow the fuel. To accomplish 'this the damper?, 'will be adjusted so as to partly uncover simul-g` 'vneously the openings d e ofthe two pipesi During the raking of the re'the dustthereof will be directed from 'the as'hpit `into the chimney or flue, as follows: The damper willi be drawn out to or turned over against the:A fopening b of the top of the Vpipe D in the res? 'ervoir, so as to cover said. opening. There'isi now acommunication between the ash-pit A and the reservoir E by means of the opening a, pipe H, and the opening d, and between the reservoir andthe combustion-chamber L by means of the openin g e, pipe J, and pipe K. The dust follows the line of said communication, and is consequently passed ont the combustionchamber into the chimney or lue.

The material of which the inclosed pipe D is composed will be preferably a good conductor of heat.

Having thus vdescribed my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The fresh-air pipe F, in combination with the pipe D inclosed thereby, and communicating with the Ventilating-register G, and with the reservoir E of a combustion apparatus, B, substantially as and for the purpose set forth.

2. The pipe D, communicating with the Ventilating-register G,in combination with the reservoir E, 'communicating with said pipe, and with the ash-pit A and chamber L of a combustion apparatus, B, substantially as and for the purpose lset forth.

l3. The reservoir E, in'combination with the pipe D, having Aopening b, the pipe H, with openings a and d, the pipe J, with opening d, andthe pipe K and combustion-chamber, and with the adjustable fdamper M, substantially as and for the purpose set forth.
